How to pick a voice

Descriptors map to delivery character: Bright and Upbeat voices (Zephyr, Puck, Laomedeia, Sadachbia) read energetic copy; Firm and Informative voices (Kore, Charon, Rasalgethi, Orus, Alnilam) suit narration and explainers; Soft, Gentle and Warm voices (Achernar, Vindemiatrix, Sulafat) fit calm or intimate reads; Gravelly (Algenib) and Breathy (Enceladus) add texture.
